Meyer Burger Investor Presentation

Race for record cell efficiencies often says little about mass production capability Mass production: average cell efficiencies HJT 21.5% PERC 20.0% MEYER BURGER 23.5% +2.0% 21.5% Compare apples with apples ☐ It is common practice to report cell efficiencies More important is resulting module power with such cells in like-for-like comparison in Wp Like-for-like means: ✓ number of cells e.g. 60 or 72 cells ✓ wafer size e.g. M2 (244.3cm 2) or M4 (258.3cm²) ✓ full-sized or half cells (the latter leading to ~5 Wp more power in 60 cell module) Some companies summarize under "PERC” any cell structure containing advanced passivation concepts such as TOPCon Especially "PERC" lab cell efficiency results usually based on scientifically optimized recipes which are hardly transferable into production environment ■ Meyer Burger's commercially reported cell efficiencies are always based on cost-competitive production-ready recipes. 2015 2016 2017 2018 Source: Meyer Burger Technology Ltd 18 Meyer Burger Technology Ltd, Presentation for Investors, Analysts and Media
